The objective of this project is to estimate a fruit demand system for the Spanish economy. For doing that, we have chosen variables that we think that influence in fruit consumption decision. On the one hand, we have chosen different variables that describe the families (age, education level, number of family members by age, place of residence and nationality), on the other hand, variables related to the market side (fruits prices and spending). Our results suggest that there are different consumption habits depending on the fruits we are analyzing, some are consumed jointly and others are substitutes. ENGLISH
